1. A contactless card, comprising:
a memory containing a plurality of keys and a plurality of key selection algorithms, wherein each of the plurality of key selection algorithms are configured to select one of the plurality of keys;
a transceiver; and
a processor in communication with the memory and the transceiver,
wherein the processor:
receives a time signal,
selects a selected key selection algorithm from the plurality of key selection algorithms based on the time signal,
selects a first selected key using the selected key selection algorithm,
encrypts a communication using the first selected key to obtain an encrypted communication, and
transmits, via the transceiver, the encrypted communication to a client device.
